Abstract

The invention relates to a method for controlling the differential pressure in a CPAP device. The differential pressure is adjusted depending on the measured ambient air pressure and/or the measured ambient temperature, thereby compensating for ambient influences during therapy. The invention also relates to CPAP devices that comprise an additional ambient air pressure sensor (9) and/or an ambient temperature sensor (11).
